The ROV II™ Mini is a smaller version of the ROV II™, the most dependable and widely-used tip contact probe on the market.

The ROV II™ Mini probe is designed with AUV and smaller ROV use in mind but can also be held by divers. The ROV II™ can be used as a "stabbing" tip-contact probe or as a proximity electrode by using a surface ground wire or diver umbilical.

The ROV II™ Mini is 15.3" long, 1.6" in diameter and weighs 0.5 lbs (0.2 lbs in water). It's rated for depths up to 3000 meters.

As with all Polatrak CP probes, it features twin elements to provide two readings for every contact location. If the readings differ substantially, the operator knows one of the elements has failed, and the survey can be completed using the remaining element. With other, single-element probes, there’s no way to tell if the readings are faulty, meaning the entire survey might have to be repeated.
